QRegExp parsing matched quoted strings

I'm trying to use QRegExp to parse a string, where each token is either separated by a space or, if the token contains a space, is enclosed in double quotes. If the token contains a double quote, the double quote is escaped with \".

so from this string

Code:

---

test "a string" "string \" escaped" 1 2

---

I'd like to extract

Code:

---

[test], [a string], [string " escaped], [1], [2]

---

I was previously using a technique stolen from this bloc post ( which apparently looks to be down right at this point ) and was using the following regex in some Flex code

Code:

---

/((")(?:\\?.)*?\2) | \S+/gsx

---

Translating that directly to QT didn't work - a assume because it uses features not available in QRexExp. Here's my little test app

Code:

---

#include <QtCore/QCoreApplication>
#include <QRegExp>
#include <QStringList>
#include <QDebug>
void test(const QString& text, const QString& pattern)
{
    qDebug() << "testing " << text << " against " << pattern;
    QRegExp rx(pattern);
    int pos = 0;
    while ((pos = rx.indexIn(text, pos)) != -1) {
        qDebug() << rx.capturedTexts();
        qDebug() << rx.cap(1);
        pos += rx.matchedLength();
    }
}
 
int main(int argc, char *argv[])
{
    test( "test \"a string\" \"string \\\" escaped\" 1 2", "([\"])(?:.)*([\"])");
    test( "test \"a string\" \"string \\\" escaped\" 1 2", "((\")(?:\\\\?.)*?\\2)");
    QCoreApplication a(argc, argv);
    return a.exec();
}

---

Any ideas on how to accomplish this? Or do I need to switch to using a character based parser?

The following pattern works for me with the input you provide and a few more I tested:

Code:

---

test(
  "test \"a string\" \"string \\\" escaped\" 1 2",
  "((?:[^\\s\"]+)|(?:\"(?:\\\\\"|[^\"])*\"))");

---

Output of qDebug() << rx.cap(1):

testing "test "a string" "string \" escaped" 1 2" against "((?:[^\s"]+)|(?:"(?:\\"|[^"])*"))"
"test"
""a string""
""string \" escaped""
"1"
"2"

Thanks, that work perfectly.
